The movie scripts are fucking hilarious! The comments he makes at the end of them are so funny. Read the hate mail, and read the script he made after reading one of the hate mails.
The ninja facts are funny, too:
Facts:
1. Ninjas are mammals.
2. Ninjas fight ALL the time.
3. The purpose of the ninja is to flip out and kill people.
Man, I had no idea ninja's were that intense!
